Canon LBP312x Sleep time and Auto Shutdown time Settings (Resoved Offline error message on the Panel)

Entering Sleep Mode

The sleep mode function reduces the amount of power consumed by the machine by disabling power flow to the operation panel. If no operations will be performed on the machine for a while, such as during a lunch break, you can save power simply by pressing on the operation panel. You can also use the Auto Sleep Time setting to automatically put the machine into sleep mode if it remains idle for a specified length of time.

Note :

When in sleep mode

●  When the machine is in sleep mode,          lights in green.

Situations in which the machine does not enter sleep mode

● The machine does not enter sleep mode when it is receiving data from or sending data to a computer, any of the covers is opened, or no toner cartridge is installed.

Selecting the Sleep Mode Level

Sleep mode can be set to 2 different levels with different energy consumption reduction effects. The factory default setting for sleep mode level is <High (Deep Sleep)>. We recommend using the factory default setting to save the most power. If you want to change the setting, follow the procedure below.

Changing Auto Sleep Time

When the sleep mode level is set to other than <Off>, the machine automatically enters sleep mode if it remains idle for a specified length of time. The factory default setting for the amount of time that elapses before Auto Sleep is performed is 5 minutes (the user setting range is 5 to 60 minutes). We recommend using the factory default settings to save the most power. If you want to change the amount of time that elapses before Auto Sleep is performed, follow the procedure below.

Automatically Entering/Exiting Sleep Mode at Specified Time

You can set the machine to enter sleep mode at a specified time. You can also set the machine to exit sleep mode at a specified time.

When You Want to Prevent the Machine from Entering Sleep Mode if an Error Occurs

By default, Auto Sleep is enabled even if an error occurs. However, you can specify settings so that the machine will not enter sleep mode when an error occurs.

Setting Auto Shutdown Time

You can configure the machine to be automatically turned OFF when it is not operated for a long time. You can also configure the machine to be turned OFF at a specified time. These functions allow you to avoid useless power consumption that occurs due to failure to turn OFF the power. By factory default, this function is enabled.
